Abstract: A semiconductor integrated circuit includes a plurality of sense amplifier units including a first group of sense amplifier units and a second group of sense amplifier units, a first data bus, a second data bus, a transfer circuit between the first data bus and the second data bus, and a data latch connected to the second data bus and to the first data bus through the transfer circuit and the second data bus. Each sense amplifier unit is connected to one of the bit lines. The first data bus is connected to each of the sense amplifier units in the first group. The second data bus is connected to each of the sense amplifier units in the second group. The transfer circuit controls the transfer of data between the first data bus and the second data bus in both directions.
